November Headline: C is closing its gap with Java
The difference between the number 1 and 2 of the TIOBE index is getting smaller. C is only a little over 1% behind Java now. Last time C and Java were so close was in 2005. Both languages show a long-term downtrend, but Java’s downtrend appears to be steeper. In two months’ time TIOBE will announce the programming language of the year 2009. Candidates so far are: C, C#, PHP and may be even Objective-C.
The TIOBE Programming Community index gives an indication of the popularity of programming languages. The index is updated once a month. The ratings are based on the number of skilled engineers world-wide, courses and third party vendors. The popular search engines Google, MSN, Yahoo!, Wikipedia and YouTube are used to calculate the ratings. Observe that the TIOBE index is not about the best programming language or the language in which most lines of code have been written.
The index can be used to check whether your programming skills are still up to date or to make a strategic decision about what programming language should be adopted when starting to build a new software system. The definition of the TIOBE index can be found here.
